i have already read in another thread 'voodoo project' that it's possible for the vsa-100 chip to use maximal 64 mb of memory, so that means that the voodoo5 5500 can be upgraded with another 64 mb. by changing the memory chip of corse.the question is; did somebody this or not ?the v5 5500 with 128 mb exist or it's a pure fiction ?i have search on the internet but i could find nothing.

i have a little experience with microcontroller, so i have thought that it my be possible to transform the v5 5500 in a v4 with 64 mb. can somebody through the software, drivers to disable one of the vsa chip, and let his memory for the other ???? , so that then will be one chip with 64 mb.sorry for my poor english .bye.

it hasnt been done yet,because it s very difficult (if not impossible).you cant make a v4 64mb out of v5 either,but you can add another 32 mb to a voodoo4 agp (there are empty sockets),if you do it right,all you have to do is modify the bios a little bit and you have a voodoo4 64mb ram.this has been completed already..

so, but what about this possibility to disable one chip, only one vsa of two, but to leave his memory operational ? ....thats a possible way to obtain a voodoo4 with 64 mb.what are you think about this ?

ok, i thought that it might be possible somehowe throught a code routine or bios settings.in the driver windows, you can choose between single chip,2x or 4x fsaa.i tought that this single chip mode can be improved like i said.what means than single chip ? a v4 with 32 mb ?can the transform and lighting implemented in the bios ?thanx.

hank did it with some old ram he had just "laying around". but what he did was piggyback the SAME size ram onto the existing ram, the only pin that he didn't solder to the old ram was the last address line on each ram and he then connected this pin to the jumper wires. there were also some resistor mods. I have a pic on my harddrive somewhere of the wires, but I don't think I ever got the resistor mods completely...... I wanted to try it out, but I don't have access to the RAM, I would have to rape another board for it. lots of work for little or no gain for me. now if I could get ahold of some FASTER and LARGER ram to completely replace what is on the board now, I would try it in a heartbeat!
